Berry French Toast Casserole

Berry French Toast Casserole is a delightful, make-ahead breakfast or brunch dish that combines the custardy richness of French toast with the sweet, tangy flavors of fresh berries. This casserole is perfect for gatherings, special occasions, or leisurely weekend mornings. The use of French bread provides a sturdy base that soaks up the egg mixture beautifully, while the berries add a burst of freshness to every bite. Let’s walk through creating this indulgent yet easy-to-make dish.

Ingredients Breakdown

  • 12-14 cups French bread: Torn or cut into cubes, providing a fluffy yet crisp texture once baked.
  • 8 large eggs: The base of the custard mixture, giving the casserole its characteristic French toast feel.
  • 2 cups 2% milk: Adds creaminess to the custard. You can substitute with whole milk or a milk alternative for a richer flavor.
  • 2 tsp vanilla extract: Infuses the custard with a sweet, aromatic flavor.
  • 1 tsp cinnamon: Offers warmth and spice, complementing the sweetness of the custard and berries.
  • 2/3 cup brown sugar: Sweetens the custard, melting into a delicious syrup as it bakes.
  • 1 cup strawberries, sliced & 1/2 cup blueberries: Provide a fresh, juicy contrast to the rich custard and bread.
  • 1-2 tbsp powdered sugar: For dusting on top of the baked casserole, adding a touch of sweetness and a professional finish.
  • Maple syrup: Served on the side for drizzling, it’s the perfect complement to the casserole’s flavors.

Preparation Method

  1. Prep the Bread: Start by cutting the French bread into 1-inch cubes. You’ll need enough to loosely fill a 9×13 inch baking dish, which is roughly 12-14 cups.
  2. Make the Custard: In a large mixing bowl, whisk together the eggs, milk, vanilla extract, cinnamon, and brown sugar until well combined. This mixture will soak into the bread cubes, creating the custard-like texture of French toast as it bakes.
  3. Assemble the Casserole: Arrange half of the bread cubes evenly in a greased 9×13 inch baking dish. Scatter half of the sliced strawberries and blueberries over the bread. Pour half of the egg mixture over the bread and berries, pressing down lightly to ensure the bread soaks up the custard. Repeat with the remaining bread, berries, and egg mixture.
  4. Refrigerate: Cover the assembled casserole with plastic wrap and refrigerate for at least an hour, or overnight. This allows the bread to fully absorb the custard mixture and meld the flavors together.
  5. Bake: Preheat your oven to 350°F (175°C). Remove the plastic wrap and cover the casserole with aluminum foil. Bake for 30 minutes, then remove the foil and bake for an additional 25-30 minutes, or until the top is golden brown and the custard is set.
  6. Serve: Let the casserole cool slightly before dusting with powdered sugar. Serve warm with maple syrup on the side for drizzling.
